Just snagged my first Datsun - it's a 1979 620 shortbed with minimal rust and a seized L20b w/ 4spd.
Looks like the Seattle area is a hotbed of Datsun culture with lots of active members and great parts collectors. Hoping to meet some of you soon.
I first need to get the project to my house and pull the motor, if the L20b looks salvageable i might just rebuild it and use it for now.
If it's shot then i would like to upgrade to a K24de - looks like a pretty straightforward swap using ]2eDeYe's mounts.
Alternatively, i have a '90 Miata 1.6l and tranny laying around that would make for a great daily engine, plus a sweet gearbox. However, theres no other documented (so far as i've seen) swaps of this. The only thing somewhat similar is Bob3's 520 including suspension, i just want the engine and tranny.
I'll most likely be lurking here for awhile as i sort out plans - hence the name "TBD".
Here are the only pictures i have thus far of the 620
Here's the current project i'm wrapping up, 1998 Subaru Legacy GT RWD track car with a high compression engine build:
